TRAFFIC DELAY DETECTION BY MINING TICKET VALIDATION TRANSACTIONS
First Claim
1. A method for detecting traffic delays, said method comprising:
- analyzing a transfer time sample from ticketing data that includes data indicative of a plurality of stops;
selecting an optimal set of stop pairs from among said plurality of stops based on a plurality of factors including a coverage, a volume and a distance between at least two stops among said plurality of stops; and
detecting a structural outlier associated with said transfer time sample in order to detect traffic delays determined from said optimal set of stop pairs selected from among said plurality of stops.

Abstract
A method, system and processor-readable medium for detecting traffic delays A transfer time sample can be analyzed from ticketing data (e.g., ticket validation timestamps) that includes data indicative of a plurality of stops. An optimal set of stop pairs can be selected from among the plurality of stops based on a plurality of factors including a coverage, a volume and a distance between at least two stops among the plurality of stops. A structural outlier associated with the transfer time sample can be then detected in order to detect traffic delays determined from the optimal set of stop pairs selected from among the plurality of stops. Note that such a structural outlier can comprise an outlier in a spatio-temporal series collected from the transfer time sample.
